OK, I can't build that at 12 lbs probably so I guess I'll have to settle for a higher wing loading.
I think you can get away with a heavier wing loading in the larger scale.
Thwing! is way cooler though and will probably have a much lower wing loading.
Yea, the beast at 42 lbs is a monster. It would be cool to have a big Thwing!
Have you read the MA Dec 2004 article Page 43? Might be worth a look. Maybe some of the Aerodynamics guys can comment on various scaling laws. Sounds like something that could go in the FAQ.
By the way you have an excellent website. I have learned much from previous visits.
